Damage buffs in Overwatch 2

The community manager said that dmg boost and discord seem to be fine atm.

On paper, Discord is theoretically weaker with 1 fewer person per team benefiting from the debuff. Thus far in our playtests, Mercy’s Damage Boost hasn’t shown any major issues. That said, there’s still a chance we end up tuning both Discord and Damage Boost down, if we see they’re causing issues in further testing.
